Core Insights - The operation of the Shiyiwei River Hub significantly enhances the capacity for floodwater drainage into the Yangtze River, reinforcing the flood safety barrier while improving shipping efficiency and ecological benefits, which is crucial for ensuring water security in the basin and supporting high-quality local economic and social development [2] Group 1: Project Overview - The Shiyiwei River Hub is the largest single investment water conservancy project in Zhangjiagang's history, with a total investment of approximately 470 million yuan [1] - The project consists of three main components: a regulating gate, a pump station, and a sluice gate, with the regulating gate featuring three openings and a total net width of 28 meters [1] - The pump station is designed to have a drainage capacity of 60 cubic meters per second, which can be activated during heavy rainfall [1] Group 2: Operational Benefits - The new sluice gate has significantly improved navigation conditions, with the sluice chamber length increased from 160 meters to 180 meters and width from 18 meters to 23 meters, allowing the passage of six vessels at a time instead of four, thus greatly enhancing efficiency [1] - The regulating gate is now in daily operation, draining water 1 to 2 times based on tide levels, effectively alleviating inland flooding during flood seasons [1] Group 3: User Impact - Local boat operators have reported substantial benefits from the new hub, as it allows wider vessels to pass directly, reducing travel distance and time significantly, which in turn lowers fuel costs [1]
